This drive takes place through the.medium of (ltEttiCllltlJlO clutches, so that only that operative memberis driven by the working shaft whose clutch is engaged. The cam is alsofast on the working shaft. As soon as this cam has rotated so for thatits projection 25 reaches a slide 26, the lattcr is moved downwzirdagainst the action of a spring. not shown, acting in the directiin ofthe arrow and by mennsof its pin 27 removes the locking lever 1.7 fromthe ratchet 5 ofthe controlling shaft before the 1 shaft 24 has rotatedone complete revolu tion.

BEST AVAILABLE COP the remainder are shown connected to thecontrollingdisk merely to indicate that quite a number of magnets maythus be controlled it throws into engagement one of the clutches bywhich the motion of the working-shaitis imparted to the variousoperative members as will be explained later with Q reference to Fig.t3. For example the controlling magnet 10 starts printing and feed,while the magnet 11 brings about wordspacing; the magnet 12 brings aboutlongi tudinal displacement of the type-wheel on the controlling shaft,and the magnet 13 the return of the carriage. Magnet 1 1 and furthe!magnets which are shown may be connected as pointed out above withsimilar devices for controlling other functions of the machine. Thisfeature constitutes one of the principal advantages of in) novelmechanism. because of permitting the control of a great number ofdifferent functions and mechanisms from one controlling shaft.

The magnets may drive the operative parts directl without an auxiliaryforce in They are connected into circuit by the controlling disk 9.which, in this illustrative embodiment, constitutes a stationarycontrolling collector whose brush-arm 15 rdt'ates with the shaft 1. Thewindings of the magnets 10 to 14 are connected withthe segments of thecollector; the current flows from the battery O to the slip-ring 145connected with the mush-arm 15, over the segment located directly underthe brush to the magnet connected therewith. and over a rotatiiw switch29 back to the battery. This rotating switch is mounted on the workingshaft A and closes the circuit only when this shaft has begun to rotate,which takes place only when the controlling shaft is stationary, andthus interrupts the circuit before the controllin shaft rotates again.Its purpose is'to avoid thetemporary excitation of all the controlling.of paper 7 when the hammer strikes.

magnets during the rotation of the controlling shaft and sparking due tobreaking the ircu t at the controlling collector.

The types (t, b, c z", y, are provided on the periphery of tl1et\;'pc-wheel 3. That type which is exactly in front of the printinghammer G is printed on the sheet The types ar arranged in several rowsoneabore another so that when the type wheel is axially shifted a shortdistance on the shaft 1 a ditlerent row of types is placed in front ofhe. hammer. This shifting of the type wheel not shown in the drawings.since it does notv form part. of my ,present inventicn and since it inre way aids the exphr nation and understanding of it. in all posill llfoi the "outrolhng shaft in which a I I t i l t I i l type is located infront of thehanin'ier the ln-ush-arm l5 conducts the current to the.lone contact segment which is connected with th magnet 10 and bringsabout printing: and teed. When the brush-arm is on one of the contacts9, however. no printing ta kes place as the electromagnets 11 to l -lconnected with these contacts bring about other operations. Therefore,that part of the 'typowhcel which is opposite the ham mer in thesepositions of the controlling shaft is provided with no types.

' second stationary collector 4-. herein i called the continuationcollector, is for energazing the arresting magnet 16 when the Icontrolling shaft is in one enactly predetermined positiou. lts segmentsare arranged in pairs. and two brushes 30 and 31 which rotate with thecontrolling shaft slide over them. The segments are connected to thecombination switches 32 in such manner that thebrushes I30, 3 areconnected in each position with a diil'erent pair of switches, by whichthey can be connected to a common line 137. in the illustrativeembodiment six switches-32 are shown; as fifteen different combinationseach comprising two members can be formed with six members, thecollector has litteen pairs of contacts; a condenser 233 which isconnected with the two brushes 30 and 31 over the arresting mag net 10and over two sliding contacts 35 is used the source of current. A secondrotating switch 3 2 which rotates with the working shaft 24 connectsthese sliding contacts in its rest position. The circuit is closed atthe moment when the brushes 30 and 31 contacttwo contact-pieces whoseappertaining switches are closed. The arresting magnet 16 then energizedfor a short time by the condenser 33 and the locking lever 17 sto as thecontrolling shaft and releases the worlting shaft. The latter shaftcloses the circuit for the controlling magnets by means of the switch29, charges the condenser over the sliding contact-pieces 3.6 by meansof the switch 34, and releases the controlling.shaftby means of the.'Bai'h 25.

In order to stop the controlling shaft in a predetermined position twoof the combination switches 32 mustbe closed, which can he done eitherby hand or by a r egj ste rbandt The switch arms carry projections 38which slide over the traveling register band 39. As soon as a. hole inthis band arrives under them they enter into the same, whereby theswitch in question is closed by gravity or other suitable means known inthe art.

As long as the working shaft-2 1: is arrested by the locking lever 17-the friction clutch through the medium of which it is driven must slide.The entire energy which otherwise serves for driving the operatingmemhers is constantly dissipated. Furthermore, the torque constantlyexercised on the shaft;

com and the detent so that an. apprecinble force is requisite forwithdrawing this detent. For this reason it is preferable to connect a.detachable coupling between the wonlcing shaft and its driving member.Fig. shows such a coupling. lhe ratch et 40 is constantly driven androtates loosely onthe working shaft 2.4. The arm 41 curryinga pin l2 anda spring this fast. on the working shaft. A locking lever -13 having oneend forn'led as a pawl is fulcrumed on the pin and under the influenceof the spring l t tends to engage in the teeth of the ratchet. but as arule itis prevented from so doing by the detent, of the lever 17; assoon as this is retracted, however, the locking), lever 43 ei'igageswith the ratchet, is driven thereby and with it the arm 4:1 and theworking shaft- :24. As soon HS one revolution is finished the lever 43is stopped by the detent 22; toting further the lever 43 is then removedfrom the ratchet, the spring 6 4- is tensioned and the working shaft. 2%remains stntioir' cry. If this shaft were now no longer sub jected toany torque the spring would tend to bring about the engagement of thepawl and ratchet, and continuous rattling of the two parts one on theother would be caused. This is avoided'when a sliding clutch(represented at 212, Fig. 6) between the working shaft and the driveconstantly transmits a torque sufficient for keeping the spring 44tensioned. In order that it be not tensioned 'too much and that the linefrom thenxis of the shaft 24 passing through the fulcrum 42in the pointof contact of'the lever 43 with the stop be not materially bent, I

provide on the arm 41 a stop 4-5 against which the lever 43 beers.

The sliding clutch which may be of any suitable construction requiresonly little friction as it does not transmit the torque to the oierstive members of the machine; it can be entirely dispensed with whenthe arm 41 is held in its disconnected position by a snap roller 46,shown in Fig.3.

The six combination switches 32 and the combination collector l in thedescribed illustrative embodiment enible the shaft to be stopped infifteen different positions. The number of positions and themanysidedness of the machine is, however, materially increased when theswitches 32 are formed as double pole switches and when, instead of two,any desired number of them are reversed for each symbol or character.When six double pole switchcsare provided 2 :64: various controllingpositions are possible.

Fig. 4 shows how the combination collector is formed and connected'withthe double pole switches in this case. The pivot points of switches 51and 52 and of and 5% are electrically connected respectively owing tothe arm 4C1 roi l l 5 fully as possible.

The conzhiimtion collector 58, shown in Fig. 5, a port of Whose developedperiphery it) comprising the seg ments 60 to ($6 is shown in Fig.4, rotates on the shaft 1 in the direction indicated by the arrow underthe statiorniry brushes 31. Of these there are in all eighteen, 2'. 6.one set of three for each of the double IJOlt switches 50 to Thetwo'outer brushes of each set are connected with the contactpieces of adouble pole switch. and the mid-' (lle brush conducts the current to thenext; segment of the collector, as clearly shown. The segu'ients are soarranged on the collector that they connect either the one or the otherof the two outer brushes of one with the middle one and, as will bereadily understood, the circuit is closed when each of the sixswitch-levers 18 directly connected over one of its contact pieces and abrush to a segment of the collector. In the drawing the. collector isshown in a position in which the circuit is closed when the switches arein the position shown. The current flows as follows:- from one pole ofthe condenser 83 over the pair of brushes 35 and the switch 34: to thedouble pole switch 50, then over the segmerit-s60 and (31 to the doublepole switch 5.1, to the double pole switch 52, over the segments 62 and63 and the double pole switches 53 and 54: to the segments 6t. and65,over the double pole switch 55 and the arresting magnet 16 and backto the other pole of the condenser. Consequently, by employing doublepole switches 50 to 55 instead of the simple switches 32, the number ofpossible positions of the controlling shaft is increased from fifteen tosixty-four. Now when some of these positions are used in theabove-described manner for adjusting and printing types, and others foradjusting operations, a part'of the type-wheel reu'uiins-empty as shownin Fig. 1. This is undesirable beciiuse the type-wheel should be ofsmall diameter as iossible on ac count of a clean impression, andconsequently its periphery must be utilized as This defect is obviatedwhen the number of type-adjustments is made equal to the number of theworking adjustments (in the present instance thirtytwo adjustments ofthetype-wheel and thirty-two adjustments of the controlling dislg) andthese are arranged alternately over the periphery of thecontrollingshaft. The types are in this event distributed uniformly onthe type-wheel, and the periph cry of the type-wheel can be fullyutilized. Such an arrangement is shown in Fig. 8 in which thetype-wheel, the controlling.collector and the ratchet for arresting thecontrolling shaft are shown developed. The type-wheel 3 has the'typesarranged in three rows one above another, the top one slides ov r thethe letter 0 advantageously with a combination collector according toprovcment consists in the ratchet 5 the-same number of functions.

All those segments located inthe extension of the middle line of a type of the type-wheel areconnected with the printing and feed magnet 15 10, while theintermediate segments are connet-ted to the controlling magnets 11, i...1 3, 1 In the drawing it is assumed that the tooth lZ-l of the ratchet 5is held by the detent 21. The letter 0 is under the 20 printing hammerand a segment, connected with the printing and feed magnet 10 is underthe sliding contact 15. As soon as the working:' shaft ll begins torotate this magnet is energized over the switch 29, and

is printed. But if the controlling shaft is stopped at the tooth 125,for example. the printing hammer is between the two letters (Z and e, asindicated by a dotted line in the drawing. An impression 30 is not madeas the sliding contact 15 does not conduct the currcnt to the printingand feed magnet 10. but to the magnet 14 which starts any otheroperation of the machine.

The arr: ngement shown in Fig. 8 can be employed both Fig. l and alsowith one according to Fig. 1. Such an arrangement can be improved stillmore, as represented in Fig. 5. The iin for stopping the controllingshaft. having only half as many teeth. in the illustrative embodimentthirty-two, instead of sixty-four, and in the machine neverthelesspossessing Namely, of thesis combination switches only five are used fordetermining the arresting positions of the controlling shaft, theseswitches being designed 17 on the drawing. These five combinationswitches thus give only thirtytwo arresting positions: in the case ofeach of them. however. both the typeavheel 211" is adjusted to a typeand the controlling: collector Qto a controlling magnet. and fordetermining whether an impression of the type or the excitation of thiscontrolling magnet is to take place the sixth combination switch 48 isused.

If the machine is used for particular l purposes, frequently elementsare necessary which sometimes have to move a larger and .These memapredetermined point. or to adjust slides serving for justification. orfor other purposes. it meshes with a pinion 101 keyed on a shaft 102. Onthis shaft is splincd conicalfriction wheel 103 which can he broughtinto engagement by a twoarmed lever 105 with a second friction wheel 104fast on a shaft 104. The latter shaft is positively driven by thecontrolling shaft as will he explained later on with reference to Fig.6. As loiig the two-armed lever 105 pulled by a spring 105 against itsstop 105" the friction wheel 103 is inoperative. As soon as anelectromagnet 1.00

Then, as soon as the controlling shaftbegins to rotate again, the shaft 102 is also driven and consequentlythe rack 100 is moved by the pinion 101 until the controlling shaftstops again. AS the controlling sha [t can be stopped at any desiredplace the rack 100 canbe shifted any desired distance. After this motionhas ended the friction clutch connecting the two shafts 104 and 102must-be disengaged; to this end. a cam 10S mounted on the working shaftis provided which temporarily releases the catch 1.07. so thatthe lever105 is pulled by its spring back into its rest position before thecontrolling shaft begins tov rotate again. \Vhcn itfirst stops and thefriction clut h is engaged, the catch 107 is released for a short time;but as the magnet 100 is still energized, the lever 105 remains in itsengaged position.

Section1" runs in bearings 266 and 209 and carries the combination collector 58(see also Fig. 5) on' which the brushes 3.1, slide. These brushes arearranged in five rows, three brushes in each row,' as is shown at ill,in Fig. (i. where thebrushholders are omitted to render the illustrationclearer. The brushes are connected with double pole switches 47. 4'7.&7, 47, 174"; the detail operation and connection of which has beendescribed with reference to Fig. at but which connection is also shownin Fig. 6. Each position of the double pole switches 47. etc.corresponds with a certain position of the combination collector 58 atwhich the circuit is closed.

The arrangement shown in Fig. (3 operates as follows: The motor 200permanently rotates through gear wheels 201 and 203', bushing 213 andthus ratchet wheel. 40. Also by means of the light friction coupling 212a slight torque is transmitted to workingshaft 24 This torque, however,is counteracted by stop of lever-17' which is the equivalent of lever 17in Figs. 1 and 5 and which is distinguished from the latter merely byits bell crank shape. Lever 17 is pivoted at 268 and is capable of beingheld in two positions by means of spring controlled roll 18. By means ofgear wheel 202 all three-sections 1. 1, 1 of the controlling shaft aredriven through the friction coupling 204 so that they rotatepermanently. It may now be assumed that double pole switches 47, 4?,etc, and also switch 48 are brought into the position shown in tion ofthe perforated strip 39 (Fig. 5). As soon as now combination collectorgets into the position shown in Fig. (5. a circuit is closed for thearresting magnet 16. The currentthereby flows from the condenser 33 overconductor 272, magnet. 1(i,conductor 273 to the first double pole switch47, thence to the left hand brush 31 of the first row; to the segment.then in contact with the brush, thence over 'the middle brush of thefirst row to the middle brush of the second row, through the secondsegment to brush of the third row, contact segment, middle brush ofthird row middle brush of fourth row. right brush of fourth row,switches 47 and 47, right brush of fifth row, middle brush of fifth row,conductor 271, brushes 35 (which are then conncctcd by rotating switch34), conductor 270 back to the condenser 33.

Rotating switch 29then causes the closing, of a circuit which energizes printing andfeeding magnet 10 which is shown in Fig. 6 without its electricconnection. For the printing of the adjusted type an eccentric ill isprovided on shaft 24. With this eccentric cooperates roller 21:") whichis carried by a lever 21G pivoted at 217.

If nowmagnet 1-. is energized lever rocks on its pivot and thereby throws thetwo tic-- tents into engagement and causes the rotation of cam oreccentric 247. This part of the structure is illustrated only thus farsince the connection between the eccentric and shaft section 1 maybe ofany convenient form to bring about the desired result. The lastmentioned construction is immaterial to the present invention. lt may bestated merely that by the shifting of shaft section 1 the type wheel. afraction of .which is shown at 3 in Fig. 8, is axially shifted withshaft section 1 so that the different sizes' ot' type or numerals may bebrought into line with the printing hammer. A particular convenientarrangement is shown in my U. S. application, Serial No. m n? filed July22, 1912.

When a line of the printed matter to be produced is completed thecarriage musti he 236. Pawl 24a is held in this engaging position bymeans of sprmgi 243. Now as soon as electromagnet 13 which is inoperative d stance from pawl 240 is energized when the controllingcollectoril (Fig. 5) closes ement with nose 289 of lever the circuit forthis magnet, pawl 340 rawn otli' nose 239 so that eccentric 23 canoperate lever 236 and so that its movement in turn can be transmitted bymeans of rod 246 pivotally attached to lever 236 to the carriage. Thedetail construction of the connection between lever 236 and the can BESTAVAILABLE COP riage is, as the carriage itself, not shown since it doesnot form any part of my invention; The illustration in Fi. Got thevarious movements which control the movement of the main elements suchas the paper carriage, the hannner and the like, are only shown so fartheir connection with the subject matter of my present invention isconcerned, and it may be stated that inthe same manner in which theeccentrics and movements ust described are controlled from workingshatt'any suitable number of similar. eccentrics may be arranged on this shaftfor controlling devices connected with themachine and necessary for itsoperation. Such eccentrics are controlled by electroinag'ncts in themanner just described, the magnets being energized by the circuitarrangements shown in Fig. 5. which. to gather with the arrangement inFig. (3. illustrate the general principle on which my invention based.

lVorking shaft 24 further carries a snail cam 25, Fig. (3, the elevatedportion of which is denoted with 25 in Figs. 5 and (3. in Fig. 5 theconnection between this cam and lever 17 has been illustrated merelydiagram I maticallv to indicate thatthcre is a mechanical connectionbetween lever 17 and the cam. wher as in Fig. (3, th actual movement asemployed in the machine is'illustrated. .ln this latter figure itwill benoted a longitunally slidingbar it; is disposed adjacent to and inparallel to the plane of cam and is also located adjacent to lever 17.The bar is spring controlled shown at 26 so that roller 26 attached atits upper end maintains contact with snail cam Adjacent to lever 15 bar26 carries a pin 2? in the path of which lever 17 is located when bar 20moves longitudinally. The arrangement of the elements just described issuch that when lever 17 in engagement at 21 with ratchet wheel 5 aspreviously described. it is disengaged therefrom by pin 27 of bar 26when the latter is drawn upward by elevated portion 25 ot' cam 25 whenthe.

latter rotates with shaft This releases the controlling shaft which aspreviously described was locked by lever 17' through the energizing ofmagnet 16. The releasing of this shaft and a drawing upward of lever 17simultaneously throws portion 22 ct lever 17 into the path of lever 43which to l a I tates with working shaft 24 and upon engagement of lever23 with stop 22., the former disengages its other end from ratchet wheelco and thereby nncouplesworking shaft 5%- ti'rom bushing 213 and thusfrom ,ear wheel 203. In the mean time the rotating switch 34 which hasrotated with shaft- 24- has, during its rotation recharged condenser 33by closing a circuit through battery B over brushes 86 (Fig. 5).

The controlling shaft drives with its see-- a plurality of segments fastof said set; a source of current and! an arresting which transmit thenotation to another pair of miter gears 26: and 264. Miter gear 264fastened on shafii' IOt previously mentioned with reference to Fig. 7where the other end of shaft 1 0% is shown. This other end, Fig. Tillustrates, carries a friction bevel wheel l0-t for the purpose previouslydescribed. Now working shaft 24 carries a cam disk 108 alsopreviouslydescribed in connection with Fig. 7. -This disk is shown inFig. 6 near the right hand end ot'shaft 2.4. \Vhenever a couplingbetween friction wheels 103, and 104-, in Fig. 7. has been broughtabout/by n'lagznet 106, this coupling is loosened at/the desired momentby means of cam disk [108 in the manner previously described. i
